Value mapping values to be reflected dynamically

Hi All,

I have a scenario where R3 entries should be reflected in value mapping dynamically for a particluar field .

Can anyone explain wht does the component SAP BASIS 7.00(NS- http://sap.com/xi/XI/System,MI -ValueMappingReplication) has the role. by generating a java proxy & deploying the jar file in visual admin helps, after this proceeding with abap mapping to retrieve the value from r3 dynamically using this MI.

Correct me if Iam wrong?

I have to schedule this evry week such tht new entries should get populated dynamically form r3 in abap mapping.
